How to Integrate Claude Code 4 With Cursor

If you’re weighing Claude Code versus Cursor (or trying to juggle both), this walkthrough shows what changes when Claude Code is fully integrated inside Cursor—so you can work with live context without constantly re-explaining your code.

Key takeaways

• Walks through setup in Cursor’s integrated terminal: updating Claude, signing in, and confirming the integration.
• Shows how the status indicator reflects the active file, enabling prompts like “what does this file do?” without naming it.
• Demonstrates line awareness: select a block of code and ask “what does this do?” with the selection as context.
• Breaks down the diff view workflow—review proposed changes, revert specific blocks, and accept/reject (with an optional auto-accept toggle), plus linking Cursor from an external terminal via /ide.
